Shark-shaped sampler to hunt down ‘fugitive’ air pollution
Industrial sites and highways could become cleaner in the future thanks to shark-shaped samplers that hunt 'fugitive' air pollutants. Scientists at Lancaster University and the Environment Agency are working together to develop a new sampler to measure levels of so-called fugitive pollutants - such as particulates, and gases such as ammonia and nitrogen dioxide.

New method for methanol processing could reduce carbon dioxide emissions
New method for methanol processing could reduce carbon dioxide emissions
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have developed a more efficient way to turn methanol into useful chemicals, such as liquid fuels, and that would also reduce carbon dioxide emissions. Methanol, which is a product of natural gas, is well-known as a common "feedstock" chemical — one that is processed into gasoline and other chemicals such as solvents, adhesives, paints and plastics.

Three touchdowns for Rosetta’s lander
14 November 2014 After achieving touchdown on a comet for the first time in history, scientists and engineers are busy analysing this new world and the nature of the landing. Touchdown was confirmed at ESA's Space Operations Centre in Darmstadt, Germany at 16:03 GMT/17:03 CET on 12 November. Since then, scientists, flight dynamics specialists and engineers from ESA, the Lander Control Centre in Cologne, Germany, and the Philae Science, Operations and Navigation Centre in Toulouse, France have been studying the first data returned from the lander.

Engineer readies for rapid discovery of metallic glasses
Engineer readies for rapid discovery of metallic glasses
Yale engineer Jan Schroers will lead a three-year, $1.2 million project intended to dramatically accelerate the pace of discovering and characterizing bulk metallic glasses (BMGs), a versatile type of pliable glass that's stronger than steel. The grant, awarded as part of the National Science Foundation's program for Designing Materials to Revolutionize and Engineer our Future, will enable Schroers' team to screen more than 3,000 potential BMG alloys in a week, a vast improvement over traditional methods that take as much as a full day to identify a single alloy.

1980s aircraft helps quantum technology take flight
1980s aircraft helps quantum technology take flight 20 October 2014 What does a 1980s experimental aircraft have to do with state-of-the art quantum technology? Lots, as shown by new research from the Quantum Control Laboratory at the University of Sydney, and published in Nature Physics today. Over several years a team of scientists has taken inspiration from aerospace research and development programs to make unusually shaped experimental aircraft fly.

Architectural engineering's Houser leads study on perceptions of LED lighting
UNIVERSITY PARK, Pa. A research team led by Kevin Houser, professor of architectural engineering, has determined that color and whiteness rendition has a profound effect on LED light source preference. The team's findings were published in Lighting Research & Technology in an article titled "Perceptual responses to LED illumination with colour rendering indices of 85 and 97" at: .

New imaging technique could detect acoustically “invisible” cracks
Press release issued: 6 October 2014 The next generation of aircraft could be thinner and lighter thanks to the development of a new imaging technique that could detect damage previously invisible to acoustic imaging systems. The nonlinear acoustic technique developed by researchers from the University of Bristol's Ultrasonics and Non-destructive Testing (NDT) research group is published in the current issue of Physical Review Letters together with an accompanying article in Physics .

Los Alamos conducts important hydrodynamic experiment in Nevada
Los Alamos conducts important hydrodynamic experiment in Nevada
Hydrodynamic experiments such as Leda involve non-nuclear surrogate materials that mimic many of the properties of nuclear materials. "This experiment ultimately enhances confidence in our ability to predictively model and assess weapon performance in the absence of full-scale underground nuclear testing," said Webster.

Bubbling down: Discovery suggests surprising uses for common bubbles Posted August 19, 2014; 09:30 a.m. by John Sullivan, Office of Engineering Anyone who has ever had a glass of fizzy soda knows that bubbles can throw tiny particles into the air. But in a finding with wide industrial applications, Princeton researchers have demonstrated that the bursting bubbles push some particles down into the liquid as well.

For stable flight, fruit flies sense every wing beat
Simulated flight without control. The model insect hovers for a brief period before succumbing to pitch instability, which leads to its tumble and fall. In order to stabilize their flight, fruit flies sense the orientation of their bodies every time they beat their wings - one beat about every 4 milliseconds.

Verifying the future of quantum computing
Press release issued: 30 July 2014 Physicists are one step closer to proving the reliability of a quantum computer - a machine which promises to revolutionise the way we trade over the internet and provide new tools to perform powerful simulations. By harnessing the strange laws of quantum mechanics, future quantum computers offer the hope of quickly solving problems that would take even the best supercomputers the lifetime of the universe to solve.

Building up bamboo
Building up bamboo
Bamboo construction has traditionally been rather straightforward: Entire stalks are used to create latticed edifices, or woven in strips to form wall-sized screens. The effect can be stunning, and also practical in parts of the world where bamboo thrives. But there are limitations to building with bamboo.

Fires are major cause of wind farm failure, according to new research
Fires are major cause of wind farm failure, according to new research
Fire is the second leading cause of accidents in wind turbines, after blade failure, according to research out today. Wind farming is one of the leading industries in the renewable energy sector. However, the industry faces a number of challenges, such as opposition by wind farm lobbyists. Today's research suggests that incidents of wind turbines catching fire are a big problem that is not currently being fully reported.

Months before their first words, babies' brains rehearse speech mechanics
Months before their first words, babies’ brains rehearse speech mechanics
University of Washington Infants can tell the difference between sounds of all languages until about 8 months of age when their brains start to focus only on the sounds they hear around them. It's been unclear how this transition occurs, but social interactions and caregivers' use of exaggerated "parentese” style of speech seem to help.

Aviation offers a way forward in biofuels research
Biofuels researchers are increasingly thinking about how the energy market is changing, which challenges them to balance the basic science of new fuels with a more holistic view of the most commercially viable ways to produce them. So when a group of University of Wisconsin-Madison researchers began looking at how to make jet fuel from biomass, they also strived to create a "techno-economic" framework that would illuminate the entire biofuels field.
